Description

Maltooctaose, a specific-length maltooligosaccharide, can be produced by PFTA (Pyrococcus furiosus)^[1].

In Vitro

PFTA (Pyrococcus furiosus) is a very special enzyme that caneasily open up the certain cyclodextrin molecules to produce specific-length maltooligosaccharides, particularly maltohexaose, maltoheptaose, and maltooctaose^[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Help & FAQs

Do most proteins show cross-species activity?
Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
